Denmark; vested in the Alien Property1 Custodian ' Application December 21, 1939,-Seral No. illlplv 6 Claims.

My present invention relates to signs,4 and more particularly to signs having' a movable text or display strip insertedy inthe v'path O f the light rays from either daylight orfarticial lights.`

Thus, the invention has Vfor its objects, rst, to produce a sign in which aV long movable vtext can be used, that is gradually moved past a'window in which'the text willbe visible either di-` rectlyvor indirectly in amirror; secondly, to construct said sign insuch a 'manner as to make it possible to place the same forvv advertising purposes in ashop window, in street cars,'.or in other places, where a small but eifective sign isr desired; third, to build a sign which needs no`care,`and which will run continuouslywhen r'st started,

by usingfonly a small amou'ntof` lelectric'current;

fourth, to produce a sign by niealns'of'which it is possible, in combination with the advertising text, to display the go'odsin a very effective .and attractiveway. f

' With these objectsin mind, Ythe sign may., in accordance with the invention, be' constructed'in different ways.

In my' said invention, 'a textstrip maybe used which is guidedover two rollers'in' on'ebight.

In' order'to attain as brilliantjan'eieet as pos- "sible,A especially when a'perforated 'strip `is fused, 'I ,may t the'gla'ss pane of thefwindow withop'- ti'cally acting 'projections for thelike, preferably lsmall hemispheres of f `aboutithe'same size as the perforations thereby the advantage Vis attained Vthat the small projections'on thefront face of the pane will have theeffect of small luminous lamps which owing to `the motionofthe strip will'havea gleaming appearance. The mirror should'be adjustable,l in such a manner that the light reflected towards" the pane will act as favourably as possible. It may be of special advantage to arrange the mirrorto be-swung in' such a manner Athat during daytimefitV can catch the Vdaylight and project thesarne through 4the holes in the perforated strip, whileduring the night it can be swung into such a position that it will -catch the lightfrom lamps disposed either within thecasing of the sign, yoroutside.the same. r 'lhe mirror maybe partly transparent, if desired, `in such a manner that light from the rearside of the mirror can also be takeninto use, and the mirror may b e connected to contacts serving lto close and break theelectric-current supply -to the lamp, in such a manner `that the same will be extinguished when the sign acts as a daylight sign.

In Vmany cases it iS important that kthe portion of the lsign that containstheopeningythrough which the text of the ,sign canine-read, should be of very small dimensions, in ysuch a manner that it easily can be disposed yat a pointat which the .text is desired `to be read. The motor with driving pulley belonging thereto,` and serving to feed theiribbon forwardly maythen be' disposed atfa hidden place. r pose such signs at points where otherwise they could not be placed, owing to the spacev they would y occupy.r This apples'especallyfto'the mounting in store windows or similar places. f

Accordihg to the invention, this 'object issttained in that a casing ".orfboxi's. iitted with 'a long and narrowbox partenclosing the'forward- `ly moving and returningjparts A4oi' ther'ibbon, and which vcon't'ainsthe openings throughwhichthe textcanberea'd. 'W f ,i

` The invention comprisesal'so special construe'- tions of the narrow box part by whichk the `field. y

of usefulness .oi the same is increased.

The box part may bedeta y l the casing encircling the drivinginotor, and may enclose a'rod disposed thereon fand supporting,`

at its free end, a springractualted supporting roller'ior the ribbon 'part v'runningforth andbackv through the box part. y .l t v V @Thus 4an easy exchange ,ofthefribbon is ren'- dered Possible, if it is desired lto alter the text.

In order that the signmayeasily be yadjusted -tofwindows o'f'various sizes, itis preferableto.

Alet the `box partV be telescopic, slot/hat thev ysame 1 can be pulled outl or pushed in, 4all according to the conditions i Spacefat'thefplace where .the n signis tobe placed.V

The box'may further ,be ntteewith iight-,ing 'devices of a kind commonlyv known.' Outside'the 'box part,' the ,ribbon may move nvany'zconven- 'tional manner. vMany y.bights may pass,v over man-y'rollerain .suchfa mariherthat a veifylong ribbon with `a correspondingl;I,V longtext can be Contained ifi the bOX 'enlosinethe .driving m0# tor. Itisv, -however,ag1so feasibletodisposealong l ribbon formingseveral bights and passing over several rollers', in' the.,lon g .and -.narrow box part.`

The entire sign with the drivingmechan'isms belonging thereto mayv also be .disposedI in a drawer.adaptedvv to he pulled `out, .and'lagain pushed into position, -in -the apparatus iny which -the sign is disposed, for instance avending machine.

' It becomes possible thereby to tlis'-A Figure 7 is a side elevation of still another ern-l1,

lbodiment of the invention.

AFigure 8 is a section, taken on the line'-- VIII-VIII of Figure 7.

The sign consists essentially of I Yfitted with a cover 2 whichin the construction shown in Figs. 1 and 2 does not cover the entire upper The drivingroller I8 may support a friction roller23' disposed outside of casing 8 or a gearwheel, which is in contact or engagement with a disc 24 which is rotatably disposed on the top side of vthe sign, and thus will be rotated simultaneously with the motion of the text ribbon. On

` the disc, articles 25 to be displayed can be placed,

side ofthe box, but leave's'an opening with a"v vided in the box, in such a manner that the same will project thev light rays forward through an opening Sinthe 'front face of the box. Just be-l hind the pane 3, a strip 'I is passed over rollers 6,' 6 and 6". The stripL I may preferably be made from an opaque material, forinstance black papen'in which a text is' produced `by perforation."f,"" l

The strip "I rshould preferably be endless, and

be moved'forward past the pane 3 by means of `a motor, disposed'in the lower part of. the box I not shown on Figs. land Insteadrzof perforated letters or thel like on the strip, transparent letters or dark letters von a transparentrb'ackground maybe used.

On account of the strip 'I being directed quite closely past the pane l3 Ano light can escape` throughiv thel pane, lwithout having passed thev disposedoutside'ofjthe box. The boxmay then Abe dimensioned insuch afm'anner that it does not take up much more space vthan the strip,

neitherA vertically nor horizontally, andthe strip maybe returnedv along' the box, onI the otherv sideoffthemirror,` asshownin Figs. 1 and`2.

\ The sign shown in'FigszBLS Vconsists mainly of 3 Ya `box 8 in whichay driving motor 9-for a driving pulley IIJ'is disposed: To the top'side'of the'box l alongbarvll is`attached`whichatits*free end carries a supporting roller I2 whichisjournalled 5 'in two plates I3 united Vby a transverse plate I 4 t inserted in a-slot I5 formed inthe end' of the Q bai-'I Iandterminatingjin a hole I6 in whicha ,Y 1 spring I 'I is inserted kwhich tendsto' press against the plate I4 and, thereby, the roller I2l in an.l outwardudirectionf. Y And endless text yribbon I8y As `it may be of importance, in many cases, that the box enclosingthe window with the stripand the mirrorshouldtake up as little space as pos-` sible, the driving motorforthe same maybe l passesaround the rollers I2 and I0. On the up- 'window-pane' 3 free, so that light fromabovecan strike an obliquely disposed mirror 4 prothe disc 24 theiarticles described in the movable text. In order to make the text visible electric lamps 29 are disposed in the box I.

f In the construction shown in Fig. 7, there is f provided, on the upper side of the motor box 8', a box consistingof three parts 26, 2l and 28 forming a telescoping long and narrow box part n enclosing the text band.` By this construction the advantagecan be attained that the length of the sign can easily be adjusted according to thespace conditions at hand, as the box part 26-28 can be pulled out or pushed together.

Sections 26 and 28 01;' the telescopin'g boxof Fig. 7 arev similar and veach are slidablyren'gaged within the central section 2I-n the manner shown in Fig.' 8. 'Ihe signA of Figs. 'l and 8. is shown asi havinga bary Il which is similar' to Vbar I`I and which carries means such as electric lamps for' illuminating the text ribbon or endless band I8` on which7 thev advertising matterappears.
